Application filed August 5, 1907. Serial No. 387,116.

" To all. whom it may concern: 1 Be it :known that 1, JOHN W. CARRAWAY,a citizen of the United States, residing at St. James City, in thecounty of Lee and State of Florida," have invented a new and usefulEnvelop, oft which the following is a specification. J-

This invention relates to safety envelops. The object of the inventionis in a novel and at once practical and ready manner to render itimpossible, without detection, to openan envelo with the envelop hasbeen made.

With the above and other objects in view as will appear as the nature ofthe invention is better understoodythe same consists, generally stated,in providing the lower flap of an envelop with two concentric slots,which may bevcurvilinear or angular, and back of which ispasted adetector, in the nature of a patch of any suitably colored paper bearingthereon any preferred legend, such as the name of the sender, thatport-ion of the detector bearing the printed legend being adapted to beattached to the sealing flap,

whereby should the flap be opened, that lportion of the detectoradhering thereto wi 1 be torn or disrupted in such a manner as to giveocular and positive evidence that an unlawful attem t to open theenvelop has been made. Tlie detector is by preference secured only atits'ends to the envelop, and the second slot is utilized to permitinsertion of the blade of a pen knife to cut away the lower and sideflaps and thus permit the seal- .ing flap to be drawn backward, wherebyan inspection may be made by the recipient or "not, should hissuspicions be aroused, the

sealingfiap has been tampered with.

Instead of employing a printed legend upon the'detector that portionwhich will be attached to the sealing flap may be provided with lines ofopenings, conforming in arrangement to the contour of the slot, theweakened linesthus provided permitting the ortion that will be attachedto the sealing a) to be torn, should the said flap be unlawfull opened.-

urther and more specific details of construction of the invention willbe l'lcrcina'fter fully described and claimed.

In the accompanying drawings forming a after it is once-sealed, and.further to-enab e. the recipient of the envelop "to ascertain withoutdestroying the safety "seal, whetheror not an attempt to-tamper byinserting the blade of a pen knife throufh part of this specificationand in which like characters of reference indicate corresponding parts,Figure 1 is a view in elevation taken from the rear side of an envelop,dis.- playing the sealing fla turned u ward, and the legend upon theetector.'- Fig. 2 is a similar view taken from the front of the envelop,a portion thereof being exhibited as torn away to display :1" 3detector. Fig. 3 is a view similar to Fig. l, of a slightly modified-t'e(. tor 6 which is preferably constructed of a thin strip of paper,of any preferred color, and that bears on that portion which will appearthrough the slot 4 any suitable legenc such as the name of the sender,or the like. Below the slot 5 and on the outer'face of the flap 3 isprint-ed the directions Cut out here. As shown in Fig. 1, the detectoris pasted only at its end portions 7 to the flaps 2, the intermediateportion being unattached, and the paste lines will be located beyond theterminals of the slot- 5, so that there will be no interference with theknife blade when it is inserted in the said slot for the purpose ofcutting away parts of the pered with.

As shown in Fig. 2 the lower wall of the slot 4 will register oraline-with the center portion 8 of the flap 1, care being taken insea-ling theenvelop that the ortlon 8 does not overlap the said slotwa 1. "When the sealing flap is attached in the usual manner, thatportion of the detector under the slot 4 will adhere to the flap so thatshould an attempt be made to open the envelop said portion will bedetached or mutilated insuch manner as to give positive proof that theenvelop has been tamperedwvith. Should the recipient have a suspicionthat an attempt has been made to o en the envelop, it will only benecessary to (eternnne this act the slot 5 and cut away those portionsof t 1e flaps 2 and 3 to which the detector isattached and then turn thesealing fiap backwards or to the position shown in Fig. 1, whereby readyinspection of the detector may be secured.

In the form of invention shown in Fig. 3, instead of having that portionof the detector under the'slot 4 homogeneous, it may be weakened by rowsof erforations 9, so that the field definedby t e openings may readilybe detached from the remainin portion of the detector when the sealingap is opened. To inspect this form the same procedure as thatabovedescribed, will be observed. v

From the foregoing description it will be seen that although theimprovements herein defined are simple in character they will bepositive in securing the results designed, and further that to adapt theimprovements to envelops' already made will require no other change intheir structural arrangement than the provision of the slots 4 and 5.

What is claimed is 1. An envelop having one of its flaps provided with alurality of slots and a detector arranged baclz of the slots and havingits end portions only attached to the envelop.

'2. An envelop having one of its flaps pro- 3mm. 1, v

vided with a urality of slots, and a detector arranged bacl; being sopositioned as that one Wall thereof will conform to the line'of thesealing flap.

3. A11 envelop having one of its fla s provided with a plurality ofconcentrica y disposed slots, a detector of readily disruptible materialsecured at its end portions only back of the slots, that ortion of thedetector under one of the legend.

4. An envelop having one of its flaps provided with two slots, and adetector secured at' its ends back of the slots, the intermediateportion of the detector be ng unattached to permit insertion of a penknife blade for the purpose of separating those portions of the envelopto which the detector is attached for the-purpose of permittinginspection of the detector.
